Brief Summary

Intellectual disabled persons faced more dental problems. According to a medical review paper of international and local studies, this group has poorer dental hygiene, more severe gum disease and more untreated caries. In 2010, a report from the guardians in Hong Kong mentioned that most adults with intellectual disability cannot clean their teeth, the have dental problems and it is very difficult for intellectually disabled students to co-operate during the dental treatment. In order to alleviate their dental problems, supervised toothbrushing programme and an oral health education talk are proposed. The investigators investigate the effectiveness of the supervised toothbrushing programme and an oral health education talk. The target group of the study is mild to moderate grade intellectual disabled students of special schools in Hong Kong. A clustered randomised controlled trial design is adopted.
